In linux kernel since version 5.1 (release Date: 2019-05-05)
This option provides a kernel module that runs performance tests
useful comparing RCU with various read-side synchronization mechanisms.
The kernel module may be built after the fact on the running kernel to be
tested, if desired.
Say Y here if you want these performance tests built into the kernel.
Say M if you want to build it as a module instead.
Say N if you are unsure.
